葛根枳椇子植物饮料对小鼠酒精性肝损伤的保护作用研究

研究了葛根枳椇子植物饮料对小鼠急性酒精性肝损伤的保护作用。采用一次性灌胃50%酒精的方法建立急性酒精性肝损伤模型，检测相关生化指标及肝组织形态，评价葛根枳椇子植物饮料的肝保护作用。与模型组比较，葛根枳椇子植物饮料中剂量组的小鼠血清中谷草转氨酶、谷丙转氨酶、总胆固醇、甘油三酯以及低密度脂蛋白水平显著降低至（19.17±6.22）U/L、（14.81± 4.61）U/L、（4.77±0.33）mmol/L、（1.92±0.24）mmol//L、（0.22±0.09）mmol/L，肝脏超氧化物歧化酶、谷胱甘肽过氧化物酶以及还原型谷胱甘肽的活性明显升高，丙二醇含量显著降低至（0.80±0.09）nmol/mg pro。葛根枳椇子植物饮料在一定程度上改善肝组织的病理变化，减轻脂肪变性及炎性细胞浸润。结果表明，葛根枳椇子植物饮料对小鼠急性酒精暴露后的肝组织具有一定的保护作用。

Research on the Protective Effect of Botanical Beverage with Pueraria Extract and Hovenia Dulcis Thunb. Extract on Alcoholic Liver Injury in Mice

In this paper, the protective effect of a botanical beverage with pueraria extract and Hovenia dulcis Thunb. extract on acute alcoholic liver injury in mice was investigated. The acute alcoholic liver injury model was established by a one-time gavage of 50% alcohol, and then the relevant biochemical indicators and liver tissue morphology were detected to evaluate the hepatoprotective effect of the botanical beverage. Compared with the model control group, the middle-dose of plant beverage with pueraria extract and Hovenia dulcis Thunb. extract can significantly reduce the levels of ALT, AST, TC, TG and LDL in the serum of mice with acute alcoholic liver injury to (19.17±6.22) U/L, (14.81±4.61) U/L, (4.77±0.33) mmol/L, (1.92±0.24) mmol//L, (0.22±0.09) mmol/L, increase the activities of SOD, GSH-Px and GSH in liver, and decrease MDA content to (0.80±0.09) nmol/mg pro. This plant drink can also significantly improve the pathological changes of liver tissue to a certain extent, and reduce steatosis and inflammatory cell infiltration. The experimental results showed that the plant beverage with pueraria extract and Hovenia dulcis Thunb. extract had a certain protective effect on the liver tissue of mice after acute alcohol exposure.
